High-stability roadblock

Abstract

The invention discloses a high-stability roadblock including a shell. Two stabilizing mechanisms are arranged in the shell; the stabilizing mechanism comprises a mounting cavity formed in the shell; the inner wall of the mounting cavity is fixedly connected with a tuning fork; a solenoid is fixedly wound on the side wall of the tuning fork; two permanent magnet plates are fixedly connected to theinner wall of the mounting cavity; an electromagnetic block is fixedly connected to the inner wall of the mounting cavity; the electromagnetic block is electrically connected with the solenoid; the lower wall of the electromagnetic block is elastically connected with a magnetic sliding plug through a tension spring; the lower wall of the shell is fixedly connected with a soft layer; the soft layerand the lower wall of the shell are jointly provided with a negative pressure groove; the lower wall of the mounting cavity is communicated with the negative pressure groove through an air suction channel; a first one-way valve is arranged in the air suction channel; an air outlet pipe is communicated with the side wall of the mounting cavity; and a second one-way valve is arranged in the air outlet pipe. According to the invention, the roadblock has good stability, is not easy to topple over, and can play a good role in prompting a driver.

Description

technical field [0001] The invention relates to the technical field of road traffic equipment, in particular to a high-stability roadblock. Background technique [0002] On the traffic road, the road is often damaged. In order to distinguish the faulty road section from the normal road section, people will set up some roadblocks on the road to remind the passing vehicles and prevent the vehicles from entering the faulty road section and causing traffic to occur. Accidents, however, existing roadblocks have the following problems: [0003] 1. The existing roadblocks only rely on their own gravity to maintain stability. However, the traffic on the road is more complicated. Once vehicles and pedestrians touch the roadblocks, the roadblocks are easily toppled or displaced, resulting in errors in the instructions of the roadblocks to the faulty road section. It affects the accuracy of roadblocks marking the faulty road section. Once vehicles and pedestrians stray into the faulty...

AI Technical Summary

Problems solved by technology

[0003] 1. The existing roadblocks only rely on their own gravity to maintain stability. However, the traffic on the road is relatively complicated. Once vehicles and pedestrians touch the roadblocks, it is easy to cause the roadblocks to fall or shift, so that the roadblocks indicate errors on the faulty road sections. Affecting the accuracy of roadblocks marking the faulty road section, once vehicles and pedestrians enter the faulty road section by mistake, it is easy to cause traffic accidents and pose a threat to people's life safety;

[0004] 2. Existing roadblocks are generally made of plastic materials. In some narrow road sections, when some vehicles pass by, due to the driver's driving skills are not skilled enough, it is inevitable that they will scratch against the roadblocks, thereby causing damage to the vehicle and causing damage to the owner. cause economic loss;

[0005] 3. Existing roadblocks are generally equipped with reflective strips to remind vehicles. However, since the roadblocks are placed outdoors for a long time, it is inevitable that some dust will adhere to the reflective strips, resulting in a decline in the prompting effect of the reflective strips, especially at night. , the light is dim, once the driver does not notice the roadblock in time, it is easy to drive into the faulty road section, causing traffic accidents
